Solution


You can first identify the multiples of 2, which are 8, 12, 18 and 36, and then among the multiples of 2 identify the multiples of 3, which are 12, 18 and 36. Alternatively, if you realize that every number that is a multiple of 2 and 3 is also a multiple of 6, you can check which choices are multiples of 6. The correct answer consists of Choices C (12), D (18) and F (36).

If any number is the multiple of both 2 and 3, this number must be the multiple of 6.

Option C, D, F are correct answers.
